Next, examples of the present application will be described in detail.
Fig. 1 is a flowchart illustrating an aggregation group creation method according to an embodiment of the present application. As shown in fig. 1, the method is applied to a network offloading device, and may include the following steps:
step 102: when the number of target member ports configured by a user for a target aggregation group is larger than the maximum number of member ports supported by a shunting device chip in the network shunting device, creating at least one sub-aggregation group associated with the target aggregation group.
In this embodiment, when the network offloading device receives an aggregation group port command configured by a user, the number of target member ports configured by the user for a target aggregation group is compared with the maximum number of member ports supported by an offloading device chip in the network offloading device.
And if the number of the target member ports configured by the user for the target aggregation group is not greater than the maximum number of the member ports supported by the shunting device chip in the network shunting device, the network shunting device normally configures the target aggregation group, and load balancing is performed on the flow.
If the number of target member ports configured by a user for a target aggregation group is larger than the maximum number of member ports supported by a shunting device chip in the network shunting device, creating at least one sub-aggregation group associated with the target aggregation group; the sum of the number of the member ports of the target aggregation group and the at least one sub aggregation group is the number of the target member ports, and the number of the member ports of the target aggregation group and each sub aggregation group is not more than the maximum number of the member ports. By dividing the target member ports configured by the user for the target aggregation group into the plurality of sub-aggregation groups, the target aggregation group and each sub-aggregation group can be supported by the shunting device chip, and the limitation of the number of the member ports of the chip aggregation port group is broken through.
For example, when the maximum aggregation member port number supported by the shunting device chip is a, and the target member port number configured by the user for the target aggregation group is B (B > a), the network shunting device reserves C (C ≦ a) target member ports in the target aggregation group, and creates n sub-aggregation groups associated with the target aggregation group, where the sub-aggregation group i includes Di member ports, and ie [1, n ∈ [1, n ≦ a ] sub-aggregation groups]Di is less than or equal to A, the number of the member ports contained in the target aggregation group and the number of the member ports contained in all the sub-aggregation groups are C + ∑ Di＝B。
The network distribution equipment records a structure body corresponding to each aggregation group, and the structure body is used for recording information of the corresponding aggregation group. The information recorded by the structure body can comprise a type mark bit; the type flag bit corresponding to the target aggregation group is a first value, the type flag bit corresponding to the sub-aggregation group is a second value, and the second value is different from the first value, for example, the first value is 1, the second value is 0, and of course, other values may also be adopted. By including the type flag bit in the structure, the target aggregation group and the sub-aggregation group are conveniently distinguished, so that whether the structure is the sub-aggregation group or the target aggregation group can be judged according to the value of the type flag bit.
The structure body may include an aggregation group linked list, and the linked list information of each sub-aggregation group may be added to the aggregation group linked list of the target aggregation group in the process of creating the sub-aggregation groups. The child aggregation groups are associated with the target aggregation group through an aggregation group linked list, and all the child aggregation groups can be traversed through the target aggregation group.
Step 104: and respectively generating corresponding equivalent policy ACLs for the at least one sub-aggregation group according to the shunting policy ACL configured by the user for the target aggregation group, wherein the matching condition of the equivalent policy ACLs and the used policy load sharing algorithm are the same as the shunting policy ACLs.
The flow distribution policy ACL may forward the flow according to a predefined rule, and in the present application, configured by a user, may redirect the packet meeting a specific matching condition to the target aggregation group.
The matching condition is configured by a user, and may be input from a specific input interface, may be a specific purpose IP, or may be a specific protocol type, which is not limited in this application.
The equivalent policy ACL is generated by the network shunting equipment, and the message meeting the same matching condition with the shunting policy ACL can be redirected to the sub aggregation group corresponding to the equivalent policy ACL in the application.
The strategy load sharing algorithm is an algorithm for balancing and sharing equipment load through scheduling, can enable equipment to achieve optimal resource use, and can select a proper forwarding strategy ACL and an output member port for a message in the application. The policy load sharing algorithm may be a polling method, a random method, or the like, which is not limited in the present application.
By setting an equivalent policy ACL which is the same as the matching condition of the shunting policy ACL and the policy load sharing algorithm, the network shunting device can support the aggregation group member ports of which the configuration number exceeds the maximum member port number supported by the shunting device chip.
For example, if the shunting policy ACL configured by the user redirects the message satisfying the condition X to the target aggregation group, the equivalent policy ACL corresponding to the sub-aggregation group i redirects the message satisfying the condition X to the sub-aggregation group i.
And when any sub-aggregation group or all member ports in any sub-aggregation group are deleted, removing the link information corresponding to any sub-aggregation group in the aggregation group linked list and the equivalent policy ACL corresponding to any sub-aggregation group.
In this embodiment, when a user configuration command deletes an aggregation group member port, it is determined whether the deleted port is a member port of a sub-aggregation group, if so, it is determined whether a member port still exists in the sub-aggregation group, and if not, the sub-aggregation group is deleted and link information and a corresponding equivalent policy ACL of the sub-aggregation group in the aggregation group linked list are deleted.
When a user deletes a target aggregation group, all sub-aggregation groups and all equivalent policy ACLs of the target aggregation group are deleted. And deleting the corresponding empty aggregation group and the corresponding policy ACL according to the user setting so as to reduce the memory occupation of the network shunting equipment.
When the network shunting equipment receives a target message meeting shunting strategy ACL matching conditions, selecting a strategy ACL from the shunting strategy ACL and the equivalent strategy ACL according to the strategy load sharing algorithm, and redirecting the target message to a specific aggregation group corresponding to the selected strategy ACL;
and selecting a member port from the specific aggregation group according to a member port load sharing algorithm configured by the specific aggregation group, so as to forward the target message through the selected member port.
According to the technical scheme provided by the application, the target member ports can be divided into the aggregation groups by creating the sub-aggregation groups and the corresponding equivalent policy ACLs, and the number of the member ports of each aggregation group is not more than the maximum number of the member ports supported by the chip of the shunt device, so that the network shunt device breaks through the number limit of the member ports of the chip aggregation group, and a more flexible flow load sharing scheme can be realized.
Fig. 2 is a flowchart of a message forwarding method according to an embodiment of the present application. As shown in fig. 2, the method applied to the network offloading device may include the following steps:
step 202: receiving a target message meeting a matching condition, where the matching condition is defined in a shunting policy ACL corresponding to a target aggregation group and an equivalent policy ACL corresponding to each sub-aggregation group associated with the target aggregation group, and the shunting policy ACL and the equivalent policy ACL also define a same policy load sharing algorithm.
The explanation of the matching condition and the breakout policy ACL, and the method for creating the sub aggregation group and the equivalent policy ACL refer to the related description of step 102 in the embodiment shown in fig. 1, and are not described herein again.
Step 204: and selecting a policy ACL from the shunting policy ACL and the equivalent policy ACL according to the policy load sharing algorithm so as to redirect the target message to a specific aggregation group corresponding to the selected policy ACL.
The working principle of the policy load sharing algorithm may refer to the related description of step 104 in the embodiment shown in fig. 1, and is not described herein again.
Step 206: and selecting a member port from the specific aggregation group according to a member port load sharing algorithm configured by the specific aggregation group, so as to forward the target message through the selected member port.
According to the technical scheme provided by the application, the target message is redirected to the corresponding sub-aggregation group through the equivalent policy ACL, so that the target message can be forwarded at the limited aggregation group member port of the chip of the network shunt equipment, and the flow load sharing under the condition of more required output member ports is completed.
Fig. 3 is a schematic diagram of a network architecture of a packet forwarding system according to an embodiment of the present application. As shown in fig. 3, the message forwarding system may include a source device 31, a distribution device 32, and a target device 33, where the distribution device 32 implements message forwarding between the source device 31 and the target device 33. The flow dividing device 32 includes a target aggregation group and a plurality of sub aggregation groups, and the number of the sub aggregation groups in the flow dividing device is not limited in this application. The sub aggregation group may share the member ports in the target aggregation group configured by the user, so that the number of the member ports that the offloading device 32 can support configuration is no longer limited to the maximum number of the member ports supported by the chip. When the number of the member ports configured for the aggregation group by the user is greater than the upper limit of the maximum number of the member ports supported by the shunting device chip, the shunting device 32 creates a sub-aggregation group and an equivalent policy ACL, when receiving the message from the source device 31, selects the policy ACL according to a policy sharing algorithm to redirect the message meeting the condition to the corresponding aggregation group, and then selects one member port according to the policy sharing algorithm of the aggregation group to forward the message meeting the condition to the target device 33, thereby realizing a more flexible traffic load sharing scheme.
In the technical solution of the present application, the limitation of the maximum number of member ports supported by a chip can be broken through by improving a target aggregation group in a shunting device, which is described in detail below with reference to fig. 4. Fig. 4 is a detailed flowchart of a message forwarding method according to an exemplary embodiment of the present application. As shown in fig. 4, the packet forwarding process between the source device 31, the splitter device 32, and the target device 33 includes the following steps:
step 402: and the user configures the number of member ports of the target aggregation group and the flow distribution strategy ACL.
For example, the user configures a target aggregation group in the network offload device, including configuring the number of member ports to 30, and configuring an offload policy ACL applied to the target aggregation group, for example, the offload policy ACL is used to redirect a packet with an ingress interface of 4 to the target aggregation group.
Step 404: and judging whether the number of the target member ports configured by the user exceeds the upper limit of the member ports supported by the chip.
For example, the maximum number of the member ports supported by the chip in the network offloading device is 8, and when the number of the aggregation group member ports configured by the user is 30, the number of the target member ports configured by the user exceeds the upper limit of the member ports supported by the chip.
If the number of target member ports configured by the user does not exceed the maximum member port upper limit supported by the chip, the network offloading device 32 forwards the traffic normally: and receiving the target message meeting the matching condition, redirecting the message to the target aggregation group through the shunting policy ACL, and selecting a member port in the target aggregation group according to a policy sharing algorithm to forward the target message to the target equipment 33.
Step 406: a corresponding sub-aggregation-group is created for the target aggregation-group.
When the number of target member ports configured by a user for a target aggregation group is larger than the maximum number of member ports supported by a shunting device chip in the network shunting device, creating at least one sub-aggregation group associated with the target aggregation group. The sub-aggregation group may refer to the related description of step 102 in the embodiment shown in fig. 1, and is not described herein again.
In this embodiment, as shown in fig. 5, a schematic diagram of a flow dividing device according to an exemplary embodiment of the present application is shown. The network shunting equipment judges that the aggregation group member port configured by a user exceeds the upper limit of the member port supported by the chip, creates a sub aggregation group 1, a sub aggregation group 2 and a sub aggregation group 3, and divides the target aggregation group member port into the sub aggregation groups. The target aggregation group has 8 member ports, the sub aggregation group 1 has 8 member ports, the sub aggregation group 2 has 8 member ports, and the sub aggregation group 3 has 6 member ports.
Step 408: an equivalent policy ACL is created for the child aggregation group.
And respectively generating corresponding equivalent strategy ACLs for the at least one sub-aggregation group according to the shunting strategy ACLs configured by the user for the target aggregation group. The equivalent policy ACL refers to the description related to step 102 in the embodiment shown in fig. 1, and is not described herein again.
In this embodiment, as shown in fig. 5, a schematic diagram of a flow dividing device according to an exemplary embodiment of the present application is shown. The network offload device creates equivalent policies ACL1, 2, 3, corresponding to sub-aggregation-groups 1, 2, 3, respectively. The equivalent policy ACL1 may redirect a packet with an ingress interface of 4 to the sub-aggregation group 1, the equivalent policy ACL2 may redirect a packet with an ingress interface of 4 to the sub-aggregation group 2, and the equivalent policy ACL3 may redirect a packet with an ingress interface of 4 to the sub-aggregation group 3.
Step 410: the distribution device 32 receives the target packet sent by the source device 31.
The offloading device 32 receives the target packet that satisfies the matching condition, where the matching condition is defined in an offloading policy ACL corresponding to the target aggregation group and an equivalent policy ACL corresponding to each sub-aggregation group associated with the target aggregation group.
In this embodiment, the offloading device 32 receives a message with an ingress interface of 4 sent by the source device 31.
Step 412: a policy ACL is selected.
And selecting a policy ACL from the shunting policy ACL and the equivalent policy ACL according to the policy load sharing algorithm so as to redirect the target message to a specific aggregation group corresponding to the selected policy ACL.
In this embodiment, as shown in fig. 5, the offloading device 32 selects an equivalent policy ACL2 from the offloading policy ACL and the equivalent policies ACL1, 2, and 3 according to the policy load sharing algorithm to forward the packet, and the equivalent policy ACL2 redirects the packet with the ingress interface of 4 to the sub-aggregation group 2.
Step 414: the member port is selected to forward the target packet to the target device 33.
And selecting a member port from the specific aggregation group according to a member port load sharing algorithm configured by the specific aggregation group, so as to forward the target message through the selected member port.
In this example, as shown in fig. 5, the offloading device 32 selects one member port from 8 member ports of the sub-aggregation group 2 according to a member port load sharing algorithm configured in the sub-aggregation group 2, and forwards the packet with the ingress interface of 4 to the target device 33.
